Title: Dual switch system for common use by track guided rail vehicles and magnetic vehicles
Inventor: SCHAFFER GOTTFRIED
IPC: E01B7/06
Filed: 1988-03-10
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a dual track system for rail vehicles and magnetic vehicles.  To enable this track system to be used in common by conventional wheel-and-track vehicles and magnetic vehicles, switches are needed by which both types of vehicle can be switched from a track on which only the one type of vehicle can run to a track which can be used by both types of vehicle.  Furthermore, the switch must be suited for providing branches in a track on which both types of vehicles can operate.  For the solution of this problem the invention provides a switch system which is essentially characterized by a flexible beam      on which a likewise flexible track section      is mounted, which is intended for common use by rail vehicles and magnetic vehicles, and by an apparatus      for opening or closing a gap      between the beam and each such track      to be traversed by the rail vehicles which permits the flexing of the beam.

Abstract: ABSTRACT OF THE DISCLOSURE            PROCESS FOR THE MANUFACTURE OF PROPYLENE                HOMOPOLYMER OF COPOLYMER PELLETS   The present invention relates to a process for the manufacture of propylene homopolymer or copolymer pellets in the presence of free radical generators so as to obtain non-sticky pellets with excellent reproducibility and to increase the melt index of the polymer during the pelletisation and of the subsequent conversion of the pellets into finished articles. The invention consists particularly in adding to the polymer two free radical generators, G1 and G2, the half-life of G2 being at least 20 times longer than that of G1 at the pelletisation temperature and in pelletising the polymer to which such addition has been made under conditions such that at least 80% by weight of G2 and not more than 20% by weight of G1 remain intact in the pellets and available for a subsequent decomposition during the conversion of the pellets into finished articles.

Abstract: ABSTRACT     A coupling system between a tool system module, such as, for example, a tool receptacle, and a machine tool, such as, for example, a spindle.  In order to provide for rapid initiation and release of the connection between these components while making large axial forces available, this incorporates a clamping system with an operating rod, by means of which a wedge drive is controlled, with which clamping elements that are provided in one of the parts that are to be coupled can be forced essentially radially outwards into suitably configured recesses in the other part that is to be coupled.  The clamping elements are formed from at least three clamp-like clamping claws that are arranged at equal angular intervals from each other, these being arranged essentially parallel to a centering extension of the tool receptacle; while being supported in a centering recess of the spindle a claw section of these clamping claws that in the coupled state lies radially within the centering extension these can be pivoted into a groove-like recess of the centering extension.  This coupling system is distinguished by great flexibility with regard to potential use and by the fact that it can be produced economically.

Abstract: (Case 8421) ABSTRACT OF THE INVENTION   A truss-type brake beam having a bent configuration in which the midpoint of both the compression and the tension members lies at a level below the ends of the brake beam.          A specially constructed strut member is disposed between the compression and the tension members at their midpoints and includes an upraised portion via which a force-transfer lever of the linkage interconnecting the respective brake beams of a truck-mounted brake assembly can be mounted to rotate above the level of the tension member.   Such an arrangement allows the force-transfer lever to be located closer to the tension member than heretofore possible, thus providing sufficient room to mount a brake cylinder in the space betwen the compression and the tension members adjacent one side of the strut member.   Moreover, the upraised portion places the force-transfer lever at a height where torque forces acting on the brake beam are virtually eliminated.

Abstract: ABSTRACT                 AMPLIFICATION OF OPTICAL SIGNALS     An AGC for a laser amplifier uses a control tone modulated onto the optical signals.  During use the modulation on the optical signals is superimposed on the drive current for the laser.  The AGC derives a control signal by detecting the modulation in the drive current, multiplying it by the drive current.  The drive current for the laser is adjusted to keep the control signal constant.  In a preferred embodiment a low level sensor detects when the control tone falls below a threshold level and switches the circuit to a default configuration.  The default configuration provides a distress signal to indicate a fault and to identify the affected amplifier.  This preferred embodiment is particularly suitable for submarine telecommunications cable which include a plurality of inaccessible amplifiers.
